REMOVAL OF SILICONES AND OTHER IMPURITIES IN PYROLYSIS OIL USING SILICA GEL MATRICES

原文（中国語）

A process to reduce siloxanes in a waste plastic pyrolysis oil composition is disclosed. The process can include contacting the waste plastic pyrolysis oil composition with a modified silica gel composition under conditions sufficient to produce a purified waste plastic pyrolysis oil composition. The purified waste plastic pyrolysis oil composition can have at least 50% by weight less siloxanes, preferably at least 60% by weight less siloxanes, as compared to the untreated waste plastic pyrolysis oil composition. The siloxanes can include acyclic siloxanes, cyclic siloxanes, or a combination thereof. The modified silica gel composition can include cobalt or iron compositions.
